Proof step 6 from proof crash-gstore-inv (previous step)

dom gstore0 ∪ elems nx = dom gstore ∪ ginval, inv(gstore0), inv(gstore \ ginval), n ∈ gstore ⊦ inv(crash(gstore, gstore0, ginval, nx)[n]), n ∈ ginval

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 7:
⊦ inv(gstore) ↔ (∀ n. n ∈ gstore → inv(gstore[n]))
Proof step 8:
dom gstore0 ∪ elems nx = dom gstore ∪ ginval, inv(gstore0), n ∈ gstore, ∀ n. n ∈ gstore \ ginval → inv((gstore \ ginval)[n]) ⊦ inv(crash(gstore, gstore0, ginval, nx)[n]), n ∈ ginval

Rule argument

spec: ablock-store-inv, inst: group-store name: inv-store seq: ⊦ inv(gstore) ↔ (∀ n. n ∈ gstore → inv(gstore[n])) subst: [gstore] → [gstore \ ginval] flags: <all paths>
